Quantized Constant Envelope Precoding with PSK and QAM Signaling
Hela Jedda, Amine Mezghani, A. Lee Swindlehurst +1
Coarsely quantized massive Multiple-Input Multiple-Output (MIMO) systems are gaining more interest due to their power efficiency. We present a new precoding technique to mitigate t…
Spectral shaping with low resolution signals
Hela Jedda, Amine Mezghani, Josef A. Nossek
We aim at investigating the impact of low resolution digital-to-analog converters (DACs) at the transmitter and low resolution analog-to-digital converters (ADCs) at the receiver o…
Spatial Coding Based on Minimum BER in 1-Bit Massive MIMO Systems
Hela Jedda, Amine Mezghani, Jawad Munir +2
We consider a downlink 1-bit quantized multiuser (MU) multiple-input-multiple-output (MIMO) system, where 1-bit digital-to-analog (DACs) and analog-to-digital converters (ADCs) are…
DFE/THP duality for FBMC with highly frequency selective channels
Hela Jedda, Leonardo G. Baltar, Oliver De Candido +2
Filter bank based multicarrier with Offset-QAM systems (FBMC/OQAM) are strong candidates for the waveform of future 5-th generation (5G) wireless standards. These systems can achie…
MMSE precoder for massive MIMO using 1-bit quantization
Ovais Bin Usman, Hela Jedda, Amine Mezghani +1
We propose a novel linear minimum-mean-squared-error (MMSE) precoder design for a downlink (DL) massive multiple-input-multiple-output (MIMO) scenario. For economical and computati…
Power- and Spectral Efficient Communication System Design Using 1-Bit Quantization
Hela Jedda, Muhammad Mudussir Ayub, Jawad Munir +2
Improving the power efficiency and spectral efficiency of communication systems has been one of the major research goals over the recent years. However, there is a tradeoff in achi…
